Request - state_code (3 letters) (like country_code)

Request - state_code (3 letters) (like country_code)
My website has 800+ drivers, they are all from the same country (Australia), so all the flags are AU.
If there was a option to display the drivers state flag it would increase the user experience (UX).
I do realise this would require quite a bit of coding + images.
Maybe just a option to select an image (icon) and overtime each end-user could submit their state names and flag.

for some reason, all requests ended up in the same thread... weird.
it's better for me if youc create issues on github instead, it's easier for me to handle each separately:
